The present inventionA relates to fa'jself'- serving' gasoline punip-and'haslfor its object to provide "a lstructure whereby al person maydrop a coin theren'fsnch asahailfdollar and pump" a" half.V dolla'rs' worth of :gasoline z into a visible measuring 'receptacle from which Che may take th'e'Qga'soline lthrough the usual'v hose,V into" h'is-"tanki This structure 'doesijiaway" with the usual attendant and is particularly' 'useful' -a'tfnight' in'sI'n-all towns l andare like.

Another very' important' obj'ect'- or thefznventon. lies in .Lthef provsiozf of a" device of tliisl'fnature f which Inajy7 be" adjusted i tof-com'- Y pensate for the varying" price Vof gasoline:

. still further important obje'cto the v inv ention lies in the provision of a mechanism of this nature which is simpleiin its Constructio'ml n. comparatively inexpensive to vmanufacture; easy to manipulate; etiicient and reliable'in use and operation, and otherwise lwell" adaptedto'the purpose forV which itis designed. r Y j c With the above andnumerous otherobjects in View as' will appearv as' theI descriptionproceeds,V the "invention-resides in certain 'novel features' of construction, andfin the'co'mbination and arrangement otparts as willV be hereinatter*more.fullydescribed and: claimed. v n v p In*l the a drawing F`gur'e 'l' isV a perspective v View Y of?! pump `equippedf with. my improved", mechanism:

Thus'when' a coinvisl dropped through :the slot 37 itl willV roll'fdown the chutey 36 and if dottedy linesf'in-Figure. ylVhen 'the coin is in thispositioniitA will'be seen that it will maintain the rod 28 with its teeth 295mmesh with the gear 2d asthe crank 25`is being-,f .i A

it is the propericoin it'willj pass tliroughfthe rbranchl 39? and takerthe position shown in rotated sothat saidrod will'be lifted for* i actuating the well known pump mechanism. As the rod'28.m0Ves-upwardly the groove 30 therein will `come opposite the coin and allow the saine to'fa'llldown outyoitsactive G0. a seen that this lcoin will'maintai'n the upper position.

Of course, any suitable receptacle maybe provided for catching the coin.

' Y Any spurious coin which may Ibe inserted vinto the chute 36 will be vattracted by the magnetr40 and shunted'through the branch 5.38. outfto the vexterior of the casing.

t As the rod 28 moves upwardly and cornes to theend of the out of mesh Vwith the gear 26 so as to fall flanges 35it will be forced down into its original. position,.-the spring "134 greatly aiding'in this operationas will he apparent. vA `member 45 is pivoted at 46 and when in the Jfull Vline position shown in Figure`2 .it willengage the rod 28 to each side, of the groove 30 andv maintain the rod -28 in-mesh with thegear 26 without the necessityY of inserting a`coin. As the rod Ymoves'upwardly thev side having the groove willV slightly swing the member .45, but the 4end 47 Vof thespring 84 willreturn thememf .ber 4 5 to its initial position when .the rod 28 `falls down. However, this member 45 is fnormally disposed in the dotted line position shown in Figure 2.

)portion ofthe riser 18 and has A memberV 48 is slidable loverthe 'upper flanges 49 to form extensions of flanges 35. This member 48.is provided with a block 50 adapted to move iii the groove 20. A set screw l is threaded through the back of the member 48 and through the. block for engaging the bottoin o-.the groover20 in order that the ineml' Eber 48. may be held in different adjusted 'positions.

It will thus be seen that the rollers 32 must passup over'the flanges 49 before 'the rod 28 is returned so that this member48 may be adjusted up and down to compensate for the different price of Vline which changes .from time to time. Ac-

cess may be had tothemember 48 through suitablefdoor'53. The downward move ment of the rod 28 is limited by a stop projection 54`provided on the riser and engageil 1 able by'onefof the-rollers 32 as is illustrated vit will be seen thatthe projection 15 will be disposed .in the groove l30 and will steady in Figure 5. Asthe rod28 moves upwardly,

`-It is thought that the construction, operation, and advantages of this invention will now'be apparent'from the detaileddescrip- It the cranlr25l is turned without the proper coinbeing inserted into the-chiite 36 it will be seen thatthe teeth 29 willY immediately come out of mesh with ther gear so that the rod-28 will not-'be moved upwardlyto-anyeffective length.' so that no unauthorizedgasoline can be rtaken from the pumping.V 'mechanisiir .IVhen the proper coin, however, has Vbeen inserted, it will be end of ltherod Q8` in mesh with the gear so that as the gear turns the rod will `move upwardly and when the coin .comes into the' groove 8O it will fall ldown andthe rollers 32 will engage theflanges 35 and said flanges 35 will maintain the teethf29 in mesh with the gear. Asthe rod moves up farther the rollers 32 will engage `'with the'lla'nges` v49 the upper ends thereof.

my inventionv the flanges 49 so that the rod f has been disclosed in detail merely by wayV of example since in actual practice 'it attains 'the features ot advantage enumerated'ias del sirable in the statement of theinvention and the above description. It willbe apparent that numerous changesfin the details of construction, and in the combination and arrangementot' parts may be resorted to without departing from the spirit or scopeofthe invention as hereinafterclaimed or sacrifieing any of its advantages.
